Given numbers are 100, 125, 673, 489
The list of prime factors of all numbers are
Prime factors of 100 are 2 x 2 x 5 x 5
Prime factors of 125 are 5 x 5 x 5
Prime factors of 673 are 673
Prime factors of 489 are 3 x 163
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 100, 125, 673, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(100, 125) = 500
GCD(100, 125) = ( 100 x 125 ) / 500
= 100 / 125
= 100
Step2:
LCM(25, 673) = 16825
GCD(25, 673) = ( 25 x 673 ) / 16825
= 25 / 673
= 25
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 100, 125, 673, 489 is 1
